Zepz is the global payments group behind WorldRemit and Sendwave, with approximately $500m in annual revenue. The group has transformed an industry once dominated by offline legacy players by moving international money transfers online, making global digital payments fairer, faster and more flexible. Today, the brands send from 50 to 130 countries, operate across more than 5,000 money transfer corridors worldwide and employ over 800 people globally. As the business scaled rapidly across markets and channels, the focus shifted towards improving marketing efficiency and ensuring growth could continue sustainably.
Zepz had strong top line momentum but faced increasing pressure to scale efficiently. With limited analytics resources and growing media complexity, the team needed better tools to control acquisition costs while maximising long term customer value. The challenge was not just understanding performance, but building a robust measurement framework that could support confident budget decisions across markets and channels. Key Pain Points: • Limited visibility into CAC control and LTV optimisation • Lack of clarity around true marketing attribution and incrementality • Need for more accurate and granular MMM outputs across corridors • Under utilisation of existing data infrastructure • Analytics resource constraints limiting speed and depth of insight
Day1Data partnered with Zepz to build an integrated measurement stack that combined long term value modelling with short term performance optimisation. The focus was on automation, accuracy and decision readiness, not one off analysis. Step by Step Programme: Predictive CLV Modelling – built a predictive customer lifetime value model in Databricks to quantify long term value by channel, market and cohort Bayesian Marketing Mix Modelling – developed a granular MMM to measure incremental impact and marginal ROI across key markets and corridors Multi Touch Attribution – implemented and automated MTA using Appsflyer to improve lower funnel visibility and day to day optimisation Data Integration & Automation – connected models into existing infrastructure to reduce manual effort and improve refresh cadence Decision Enablement – translated outputs into clear recommendations for budget allocation and CPA reduction
• Fully automated MTA and CLV models delivering high accuracy and consistency • Improved confidence in channel level performance and incrementality • MMM driven recommendations that reduced CPAs by 4% in a key market • Stronger alignment between acquisition efficiency and long term value • Reduced dependency on manual analysis despite limited analytics resourcing By combining CLV, MMM and attribution into a single decision framework, Zepz unlocked more efficient growth while maintaining speed and control across a complex global marketing operation.
